Title: Radio receivers
Inventor: VEEN ALBERTUS CAREL VAN DER
IPC: G08B3/10
Filed: 1968-09-30
Abstract: 1,237,086. Radio signalling; inductive signalling. MULTITONE ELECTRIC CO. Ltd. 17 Sept., 1969 [30 Sept., 1968], No. 46357/68. Headings H4L and H4U. A receiver for use in a radio or inductive staff location system includes a tuned input stage providing an output only on receipt of a transmitted pulse of frequency appropriate to the receiver, which is supplied to a first monostable circuit 2, including a timing network 11, is differentiated at 3 and is supplied to a second monostable circuit 4 having a timing network 12, the output of monostable 4 starting an audio oscillator to energize a transducer producing an audible signal. In operation, when a signal is supplied by the input stage the monostable 2 is triggered to its unstable condition where it remains for a period determined by network 11, this period being long compared with the period of the frequency used for the transmitted pulses, but short compared with the duration of a pulse. The monostable 2 therefore is triggered many times during a signal pulse and its output, which is a square-wave of positive polarity, is differentiated to provide a short negative-going pulse from its trailing edge to trigger the monostable 4 to its unstable state for a period determined by network 12 so that the audio oscillator operates for this period, which is independent of the duration or level of the transmitted pulse. Provision may be made for the reception of speech signals.

The speed of a synchronous motor M is regulated by controlling the firing times of controlled rectifiers connecting the motor in groups 1, 2, 3 to an alternating supply by use of first pulses derived from the supply and second pulses, obtained from a derivation circuit 5 connected to the output of a rotor position sensor 4, and occurring at the time of each change in the output of sensor 4. The control system 6 comprises a first series of gates (depicted in block form in Fig. 2, not shown) arranged to pass the first series of (phase adjustable) pulses to the appropriate group 1, 2 or 3 of controlled rectifiers depending on the output of the rotor position sensor 4 and a second series of gates arranged to pass the second series of pulses from the derivation circuit 5, via one of the first gates, to one of the rectifiers connected to a respective one of phases R, S, T, under control of current transformers AR, AS, AT, i.e. depending on which of the phases is supplying current at that instant. The motor may run at super-synchronous speed and may be used for running-up and synchronizing hydroalternators, compensators or gas-turbines.

Abstract: 1,130,575. Conductive glaze. PLESSEYUK. Ltd. 11 Nov., 1965 [25 Nov., 1964], No. 47854/64. Heading C1M. [Also in Division H1] Resistors are formed by a glaze containing conductive material by dissolving the inorganic ingredients from which the glaze is to be formed, dissolving also an element or compound from which the conductive material results, evaporating the solvent and firing the remnant as a film on a substrate or casting it in a mould with fibrous reinforcement material. The solvent may be evaporated after the solution has been coated on to a substrate by screen printing, dipping or spraying. Materials used to form the glaze may be (for lead borosilicate glass) lead compounds such as the basic acetate, naphthenate, oleate, resinate, stearate or lead naphthenate solution, boron compounds such as triethylborate and silicon compounds such as ethyl silicate or silicon ester. The conductive material may result from the inclusion of a compound such as a carboxylate, naphthenate or resinate of metals such as gold, indium, nickel, palladium, platinium, rhodium and ruthenium or ruthenium trichloride. Thickeners and hydrolysing agents may be used to give the solution suitable consistency for application. Substrates of steatite or alumina may be used. Examples are given involving an initial mix of glaze forming compounds in benzyl alcohol, followed by subsequent adding of methyl alcohol and water with further prolonged mixing the resultant product being combined in wet or dry form with ingredients chosen to provide (after firing) conductivity in the glaze in a solvent and chloroform or methyl ethyl ketone and possibly cellulose acetate butyrate or terpineol. Firing may be in air, air and steam, steam/nitrogen or 10% hydrogen and 90% nitrogen. Firing temperatures and times and various parameters such as temperature coefficients are given. The resistors may be used for potentiometers.

Abstract: 1,245,768. Phase-lock loops. WESTERN ELECTRIC CO. Inc. 9 Oct., 1968 [10 Oct., 1967], No. 47867/68. Heading H3A. A phase-lock loop, Fig. 3, comprises: a comparator 12 for comparing an input E t  with a reference E f ; a clock source 24 having a variable repetition rate (e.g. at discrete frequencies F o  and F 1 ); a gate 14 controlled by the output from comparator 12 for varying the repetition rate of the clock source; a counter 20 which counts the clock pulses; and means responsive to the count to produce the reference signal E f . Comparator 12 is an EXCLUSIVE- OR and voltage E 0  has a mark/space ratio proportional to the phase difference between E i  and E f . During the "mark" period output F 1  is fed to register 20, and during the "space" period output F o  is fed to register 20. The register count is thus proportional to the phase difference. In an nth order circuit, Fig. 1, n registers 20... 22 and n + 1 clock outputs F o  ... F n  are employed. During the first cycle of E o , the register 20 counts as before. At the end of this cycle, the contents of this register are transferred to the second register 21 and are added to pulses fed into this register from F 2  during the second "mark" period of E o . The sequence repeats until the nth register 22 produces the required output pulses for AND gate 28 to trigger bi-stable 13 and produce the required E f  pulse. A second order circuit is also described, Fig. 4 (not shown).

The apertures are etched into the laminations, prior to joining of the laminations by high-temperature soldering or by pressure. Parts 29, 30 of the return channels extend into the cover plates, so that each lamination is a single-piece component prior to the joining, despite its apertures. The cover plate depressions 31, 32 provide additional passageways for the gas, the return channel parts 29, 30 are vented at 40, and the thermal mass of the oscillator is reduced by cut-out portions 35, 36, all of which features ensure that the oscillator frequency (which may be measured by a quartz crystal pressure sensor 23 coupled to an oscillograph) can follow rapid temperature changes.

As shown in an exploded perspective view, the material to be sprayed is supplied to a chamber 11 in a manifold 10 under pressure through a conduit 13, the material then passing through a filter 20 in a plate 20, through openings concentric with orifices 41 in an inlet plate 30 at the bottom of an elongated slot 31, through the orifices 41, through openings 43 in a spacer plate 42, through the openings in the charge ring plate 50, through openings 61 in a clamp plate 60 and then between the electrodes 70 to the web to be coated. A catcher 81 is positioned below the electrodes 70 in a position such that it catches on a blade (not shown) the drops of spray deflected by the electrodes 70, but allows undeflected drops to reach the web, whether or not a drop is deflected depending on whether or not the charge ring through which it passed in the plate 50 gave it a charge, this being decided by the control unit 56. A clean out port in the inlet plate 31 is provided shown sealed by a plate 36, air pumped through the orifices 41 and cleaning fluid pumped through the filter plate exiting through this port in the process of assembling the spray device.
